To further investigate the mechanism characteristic of CVT in transmission process

introduction of elastic deformation effects in the belt drive belts

and taking into account the friction between the belt and layered belt and pulley

the steady-state operation of the belt drive model is established to analyze the system drive belt friction

tension and velocity variation in the steady state operation of the process at different locations and different pulley ratios under.The results show that in the capstan area

when the friction coefficient of the friction contact surface is not large enough

the inside of the belt will absorb the large load

the friction coefficient is large enough

the layers of the belt will be approximately the same load balancing

the opposite region of the driven wheels

innermost conveyor drive speeds up and from the inside out at the driving wheel area gradually decreased with the increase of the coefficient of friction between the belt and pulley

belt speed layers increased

the area opposite the driven wheel.When the spacing between the pulley system fixed in the belt drive for the moment than the minimum length

with transmission ratio changes

the length of the belt will show an increasing trend.
